About Grapefruit juice, red, not fortified, not from concentrate, refrigerated

Red grapefruit juice, squeezed from the rosy-fleshed variety and sold chilled rather than reconstituted from concentrate, has a brighter, slightly sweeter edge than the paler white grapefruit. This entry is the unsweetened, unfortified version — just the juice, with nothing added back in.

It is one of the lighter everyday juices, at about 41 calories per 100 grams, which works out to roughly 100 calories in an 8-ounce glass. Most of that is natural fruit sugar, balanced by grapefruit's signature tartness. A glass also delivers a solid dose of vitamin C and useful potassium, and the red varieties carry lycopene and beta-carotene, the pigments behind their color.

One thing worth knowing: grapefruit and its juice can interact with a number of prescription medications, changing how the body handles them, so anyone on regular medication may want to check with a pharmacist. For everyone else it is a refreshing, vitamin-C-rich way to start the day — though eating the whole grapefruit adds the fiber that the juice leaves behind.
